She has over 25 years of experience in the design of complex structures worldwide. With a keen appreciation for design and value, she has worked on iconic buildings around the world. She sits on numerous national industry boards and teaches at the Yale University School of Architecture. She frequently writes and presents on topics related to innovation and technology in engineering and architecture. Her firm, Hatfield Group focuses on synthesis of engineering and architecture, putting client value first. Hatfield Group, uses bespoke engineering design and innovation to provide value and achieve their clients’ goals.
Her experience includes the new $1.5B home of the NFL’s Atlanta Falcons, the Mercedes Benz Stadium, with a never been done before aperture style retractable roof. Other projects include the new headquarters for PNC Bank in Pittsburgh and the 9/11 Pavilion at the World Trade Center site in New York City.
She was featured on the television programs on the Science Channel “World’s Greatest Stadium” and on the History Channel’s “Building Giants”. She was named a “Power Player” and “Game Changer” by Sports Business Journal magazine. She is both a licensed engineer and architect, plus a LEED BD+C certified professional.
This presentation will share insights into the design approach of large scale, long span structures. A discussion of long span design, new materials and the implementation of new technology will be shared from the initial concept phase through construction. Stadium designs will be featured, including the new Mercedes-Benz Stadium in Atlanta, that has a host of engineering innovations in its pioneering design. The 72,000 seat stadium features a 723' long span steel retractable roof with 8 moving petals that open like a camera lens. The roof supports at the center of its span a 360-degree LED video “halo” scoreboard, the largest in sports. The geometrically complex facade is clad in single skin ETFE, a light weight and translucent material. In addition, the building is the first LEED Platinum stadium.

“Investigation and Treatment of a Swallvette*”
aka: Sinkhole Remediation at the National Corvette Museum
Michael J. Marasa, PE, BDM
Hayward Baker Inc.
Hayward Baker is the largest geotechnical specialty contractor in the country providing services to all types of clients in all types of ground conditions. This one-hour presentation discusses various aspects of the sinkhole collapse at the National Corvette Museum in Bowling Green, KY. However, it is not a highly technical analysis or case study. Rather, it gives due respect to the historical significance of the vehicles impacted by the collapse and includes bits of geology, history, engineering, anecdotes, photos, comedy, lore and an infatuation with America’s sports car.
At 5:38 am on the morning of February 12, 2014, security cameras recorded the collapse of the display floor and development of a sizable sinkhole inside the museum. Eight treasured and unique corvettes were “swallowed” by the cavity. Within 24 hours, a team had been assembled to stabilize the area, assess the short term risk, evaluate procedures to safely remove the automobiles, and develop a plan for exploration and permanent repair; essentially “vetting” solutions to the complex issues.
Team members represented a wide range of professionals representing construction, engineering, surveying, geology and environmental consultants, academic experts and state geotechnical and safety officials. Data acquisition included large diameter drilled holes, laser surveys, micro gravity study, physical cave exploration, borehole cameras and literature research.
All of these aspects were executed amidst worldwide attention and media chaos. Live webcams were installed, hourly Facebook postings, YouTube videos and about every other avenue of communication known to man were employed.
Every aspect of study and repair entailed moderate to very high degrees of risk in all categories. The expertise and determination of the team conquered all of the obstacles in as timely a manner as possible attempting to maintain economical approaches whenever possible.
*Loosely derived from Merriam Webster “swallet + corvette”
